This is a fairly expensive pen, at $10.49 for 4. This is a capped pen, that is fairly visually attractive, with a nice grey and silver color scheme. The clip is firmly attached to the cap and doesn't wiggle. Inside the cap is a spring loaded seal so that the tip doesn't dry out.
The grip is made of the same plastic as the cartridge, so it's not cushioned. There is a subtle diamond texture to provide some slip resistance. Inside the grip is the visible air flow mechanism, a set of thin ribs and vanes. The liquid ink capacity is pretty large, so this should write for a long time. (Perhaps I need to invest in a pen plotter to provide measured line lengths)
The pen itself is very light, and posting the cap changes the balance slightly, but not enough to be annoying. Posting the cap on the back of the pen takes a distinct push to snug it down. Once it's on, the cap is held firmly in place, and takes a real pull to get it back off.
As to the writing, it's pretty good. Ink start up is immediate, and the pen leaves a dark line, without any gaps or streaking There isn't a lot of feedback from the pen as you write, no slight vibration as you move across the paper, but it writes well.
